HABA HC7021
AlZn5.5Mg1.5
Milled aluminium casting plates,
EN AW-7021
HABA HC7021 is a age-hardened, horizontally cast aluminum plate that meets the most stringent requirements for strength and machining properties. The special manufacturing process is according to strict HABA factory standards. These standards apply to all process steps and are a guarantee for the excellent properties, homogeneous microstructure, and gas- and vacuum tightness. Temper T73 ensures the best corrosion resistance.
APPLICATIONS
- Base plates
- Rotary tables
- Table tops
- Foam, deep-draw and sample moulds
